LuaLogging provides a simple API to use logging features in Lua.
|
||
|
|
Its design was based on log4j. LuaLogging currently supports,
|
||
|
|
through the use of appenders, console, file, rolling file, email, socket and sql outputs.
|
||
|
|
|
||
|
|
Current version is 1.2.0. It was developed for Lua 5.1.
|
||
|
|
|
||
|
|
LuaLogging is free software and uses the same license as Lua 5.1. It is part of the Kepler Project.

============================================
|
||
|
|
|
||
|
|
The changes that I have made allow more complex log message formatting to be done only when
|
||
|
|
that log level is enabled. This will decrease the impact of logging statement when their level
|
||
|
|
is disabled.
|
||
|
|
|
||
|
|
* Use string.format() style formatting:
|
||
|
|
|
||
|
|
logger:info("Some message prefix: val1='%s', val2=%d", "some string value", 1234)
|
||
|
|
|
||
|
|
* For more complex log message formatting:
|
||
|
|
|
||
|
|
local function log_callback(val1, val2)
|
||
|
|
-- Do some complex pre-processing of parameters, maybe dump a table to a string.
|
||
|
|
return string.format("Some message prefix: val1='%s', val2=%d", val1, val2)
|
||
|
|
end
|
||
|
|
-- function 'log_callback' will only be called if the current log level is "DEBUG"
|
||
|
|
logger:debug(log_callback, "some string value", 1234)
|
||
|
